I don't own a vacuum sealer. I figured I'd never use it enough to justify spending that kind of money on one (the run about £100 here for a basic model with no attachments and the bare minimum of bags).
To begin with I managed to get by, sucking the air out of the bags myself. Lovely, I know, but in a pinch everyone's done it.
Anyway, I decided to have a go at OAMC about five or six months ago to see if it would work for me and my family. It didn't, I am no where near organised enough to remember to take the things out of the freezer to defrost.
Have you ever tried blowing up balloons for a child's birthday party all by your lonesome and after the first few you start to feel a little, well, lets just say, a little drunk, tipsy, rightly, three sheets to the wind. Same goes for sucking the air out of something.
Then the unthinkable happens, there I am bagging up dump chicken and sucking the air out, when I get a mouthful of the stuff, raw chicken juice an all. I know this has happened to other people and even when it is something that has been cooked, if your not expecting it, it is not a pleasant thing to happen.
So, the easy way to vacuum seal (I know, I waffle on sometimes, I'm getting there I promise). When your planning on bagging things for the freezer, fill your sink right up with water. Once the goodies are in the bag, dunk it in the water until the water is just below the zip lock. The pressure of the water forces all of the air up and out of the bags and all you have to do is close the zip. Easy as that, give it a go.
I don't OAMC anymore, but I do once a month prep and this still works for me.
